. same, reference being had to the accompanying drawings, and tocharacters of reference marked thereon, which form a part of thisspecification.

This invention relates, generally, to improvements in eye-glasses; andthe same is in the nature of a division of my former application for apatent for improvements in mountings for eye-glasses, filed Nov. 27,1906 Serial No. 345,279, such mountings being in the general form of anose-bridge or support, with the end-portions of which the respectivelenses are connected in a pivotal or oscillatory relation, by means ofthe eye-glass studs and their boxes, so that each. lens is capable of aseparate pivotal movement, centrally about its axis of pivotalconnection with the'end-portion of the nose-bridge or support, therespective nose-plates or guards, While having a rigidly fixed relationto their respective lenses and the studs and their boxes, being capableof oscillatory movements in opposite directions with relation to eachother, and about the points of pivotal connection at the respectiveend-portions of the nose-bridge or support.

In the fitting of eye-glasses, as is wellknown to Opticians, it isessential for the best results that not only should the focal center ofeach lens coincide with the pupil of the eye, but also that the major orhorizontal axis should, when the glasses are arranged upon the nose,register in parallelism with the major axis of the eye-ball; and,furthermore, it is essential, that the holding-portions of thenose-plates or guards should bear upon the opposite sides of the nosewith the least possible pressure, and stillhold, to obviate anydiscomfort and pain to the wearer of the glasses.

' This invention, therefore, has for its principal object to provide anovel mounting for eye-glasses having the above stated purposesconstantly in view; and, moreover, this invention has for its furtherobject to provide a simple arrangement of bridge-piece adapted to restdirectly upon the nose, in place of the usual connecting barspring, saidnose-bridge being provided at its respective end-portions with pivotswith which the respective lenses by means of their studs arepivotally'connected, said studs and their boxes, as well as theirrespective nose-guards being spring controlled, substantially ashereinafter more fully set forth, whereby the major or horizontal axesof the two lenses are angularly disposed, upon the inner side of theeye-glasses, and out of the parallelism with the major axis of theeye-balls; but when placed upon the nose, all the parts which arepivotally connected with the pivot-portions of the ends of thenose-bridge or support, moving outwardly so as to bring the major axesof the lenses into such parallelism with the major axes of theeye-balls, the nose-guards or plates at the same time moving in outwarddirections, all to the great comfort and benefit of the wearer of theglasses, and less liability of abrading the skin and preventing theresulting soreness of the nose.

The broad idea which underlies the present invention as particularlyenumerated will be clearly evident from the following detaileddescription of the same.

With the various objects of my present invention in view, the inventionconsists, primarily, in the novel eyeglasses hereinafter set forth; and,furthermore, this invention consists in the novel arrangements andcombinations of the various devices and parts, as well as in the detailsof the construction of the same, all of which will be hereinafter morefully described, and then finally embodied in the clauses of the claimswhich are appended to and which form an essential part of thespecification.

The invention is clearly illustrated in the accompanying drawings, inwhich Figure 1 is a top-edge view of a pair of eyeglasses embodying theprinciples of this invention, the parts being shown in their normallyangular initial positions with relation to the rigid nose-bridge, beforethe arrangement of the eye-glasses in position upon the nose; and Fig. 2is a similar view of the same parts, showing the lenses and the pivotalsupports moved into an outward angular relation, prior to the adjustmentor placing of the eyeglasses in position upon the nose, both of saidviews being made on an exaggerated scale. Fig. 3 is a detail sectionalrepresentation, taken on line 33 in said Fig. 1, but on a still furtherenlarged scale, with the lens represented inpart only; and said viewshowing in elevation the lens-support and one form of nose-plate orguard, with the spring for retaining the lens and lens-support in theirnormal initial positions indicated in said Fig. 1. Fig. 4 is ahorizontal section taken on line 44 in said Fig. 3, looking in thedirection of the arrow 00, the nose-plate or guard being omitted fromsaid view. Fig. 5 is a sectional representation of said parts, saidsection being taken on line 55 in said Fig. 4, looking in the directionof the arrow y; and Fig. 6 is a top-edge view of one form of the pivotalsup ort between the lens and the nose-piece. *ig. 7 is a view similar tothat shown in said Fig. 4, but of a slightly modified construction.

Similar characters of reference are employed in all of the abovedescribed-views, to indicate corresponding parts.

Referring now to the several figures of the drawings, thereference-character 1 indicates the complete mounting, and the samecomprises a suitably bent or curved nose-bridge or support 2, the lenses3, the lens-supports 4, and the nose-plates or guards 5, all beingarranged substantially in a manner to be hereinafter more particularlydescribed.

The nose-bridge or support 2, as will be seen more especially from Figs.1 and 2 of the drawings, is usually made in the form of a wire-bar, andis suitably bent at its ends, as at 6, to provide holding-portions,forwardly projecting members 7 extending from said bent-portions 6. Thesaid members 7 are substantially in the same horizontal plane of thenose-bridge 2, and at its free end each member 7 is formed with adownwardly extending and substantially right-angled pivotpost or element8. Suitably secured upon the edge of each lens 3, by means of a screw 9and the stud-straps 11, is a stud 10, each stud being preferably madewith a shank-like member 13 u on which is arranged an element 14, whicmay be termed a box. This element 14 is made, preferably, in the mannerillustrated more particularly in Figs. 4, 6 and 7 of the drawings, inwhich case it consists, essentially of a pair of perforated plates 15and 16 fitted over said shank 13 said plates being doubled upon eachother substantially in the manner shown, so as to provide at theirdoubled-over edge a sleeve-like bearing or pivot-receiving member 17.

' As indicated in Fig. 4, the plate 16 may be 65 provided with aright-angled projection or shoulder 18; or, if desired, the other plate15 may be provided with a right-angle projection or shoulder 19 whichprojects beyond the edge of the plate 16 substantially in the mannerindicated in said Fig. 7 'of the draw.- ings. These'projections 18 and19 with the outwardly extending surface-portions 20 of the sleeves orpivot-members 17 provide receiving spaces into which thefree-end-portions of the shanks 13 extend, to receive the perforatedend-portions 22 of the members 21 of the nose-plates or guards 5, thesaid shoulders and the projecting surface-portions of the sleeves orpivot-members 17 preventing said end-portions 22 from turning upon theirshanks 13, as will be clearly evident. Suitable screws 23 are employedfor suitably securing the parts in their assembled relations. Suitablyarranged between each pair of fiat-faces of said plates 15 and 16, andencircling the shank 13, is an eyeportion or loop 24 of a spring 25,said spring consisting, preferably, of a single coil 26, provided withone leg or element 27 of which the loop 24 forms a part, and withanother leg or element 28 which extends in an upward direction and hasits end-portion 29, which is preferably bent or curved, as shown,arranged in retaining engagement with a holding-portion 6 of thenose-bridge or support 2, substantially in the manner illustrated. Froman inspection of said Figs. 4 and 7 of, the drawings, it will be clearlyevident, that when the screw 23 is tightened the eye-portion or loop 24of the substantially fiat spring is firmly clamped between and securedagainst displacement from the said plates 15 and 16, and each lens ispivotally connected by the lens-supports thus provided with eachpivotal-post or element 8 of the nose-piece or support 2, so as to swinghorizontally with relation to the vertical plane of said nose-bridge orsupport 2. At the same time, the said noseplates or guards 5 beingdirectly connected with said lens-supports, the outward movements of thelenses and their supports, also cause similar movements in outwarddirections, of said nose-plates or guards, whereby the eye-glasses arereadily adjusted in their wearing positions upon the nose, withoutdiscomfort and without abrading the skin. That the said sleeves orpivot-members are secured in their rotative positions upon saidpivot-posts 8 against any vertical displacement, the lower freeend-portion of each post or element 8 is preferably made to projectbeneath the lower open end-portion of each sleeve or pivot-member, andis provided with brought in retaining engagement to limit theoscillatory movements of the parts, as will be clearly understood.

I claim:

In a mounting for eye-glasses, the combination, with a nose-bridge, anda lens-support pivotally connected with said nosebridge, of a springconsisting of a coil and a pair of upwardly extending end-members, oneof said end-members bearing upon said lens-support and the otherend-member bearing upon said nose-bridge, said coil being arranged at aoint below said lens-support and the nose-br dge, and entirely free fromsaid members, so as not to interfere with the pivotal movements of thelens-support, substantially as and for the purposes set forth.

In testimony, that -I claim the invention set forth above I havehereunto set my hand this 13th day of May, 1907.
